2003 Toyota 4Runner ProblemsBrake master cylinder may need replacing at 125,000 miles
At 125,000-150,000 miles, the Master Cylinder may need replacing. It is critical to adjust the brake pedal to Master Cylinder pushrod clearance or the brakes will drag and over heat.
If the car will not start, the most likely problem is worn or corroded solenoid contacts in the starter. Usually, these parts can be replaced without purchasing a new starter.
Usually by 150,000 miles the AC system will need some attention, especially in climates where it is used often. Our technicians tell us that it is best to service the AC system every 2-3 years. This keeps the moisture in the system at a minimum which extends the life of the components.

2003 Toyota 4Runner RecallsAccelerator Pedal May Stick Open
The accelerator pedal can become trapped under an unsecured or incompatible floor mat. This can cause the accelerator pedal to stick in the wide open position, increasing the risk of a crash. At this time, the remedy plan is still under development, but will most likely involve modification or replacement of the accelerator pedal and Toyota all-weather floor mats. No schedule of owner notification is available at this time. The Toyota recall number is 90L; the Lexus number is 90LG.
Toyota has recalled certain 2003 4Runner and Highlander trucks because the lug nuts used for upgraded alloy wheels are not suitable for the spare tire and wheel. If the existing lugs are used, the spare tire may loosen and come off. Dealers will provide owners with newly designed lug nuts, a warning label for the spare wheel, and an owner's manual addendum.
Toyota has recalled certain 2003 4Runner trucks because the diaphragm on the fuel pulsation damper may leak, which may cause a fire in the engine compartment. Dealers will replace the fuel pulsation damper.
